1 / 8 page . INPUT OFFSET VOLTAGE : 3mV max. OVER TEMPERATURE . FREQUENCY COMPENSATION WITH A SINGLE 30pF CAPACITOR (C1) . OPERATION FROM ±5V to ±15V . LOW POWER CONSUMPTION : 50mW AT ±15V . CONTINUOUS SHORT-CIRCUIT PROTEC- TION . OPERATION AS A COMPARATOR WITH DIFFERENTIAL INPUTS AS HIGH AS ±30V . NO LATCH-UP WHEN COMMON-MODE RANGE IS EXCEEDED . SAME PIN CONFIGURATION AS THE LM101A DESCRIPTION The UA748 is a general purpose operational am- plifier built on a single silicon chip. The resulting close match and tight thermal coupling gives low offsets and temperature drift as well as fast recov- ery from thermal transients. . Short-circuit protection . Offset voltage null capability . Large common-mode and differential voltage ranges . Low power consumption . No latch-up The unity-gain compensation specified makes the circuit stable for all feedback configurations, even with capacitive loads. However, it is possible to optimize compensation for best high frequency performance at any gain. The low power dissipation permits high voltage operation and simplifies pack- aging in full-temperature range systems. 1 2 3 4 8 6 5 7 PIN CONNECTIONS (top view) ORDER CODES Part Number Temperature Range Package ND UA748C 0 oC, +70oC •• UA748I -40 oC, +105oC •• UA748M -55 oC, +125oC •• Example : UA748CN N DIP8 (Plastic Package) D SO8 (Plastic Micropackage) PRECISION SINGLE OPERATIONAL AMPLIFIER UA748 December 1997 1 - Offset null 1 / frequency compensation 2 - Inverting input 3 - Non-inverting input 4- VCC - 5 - Offset null 2 6 - Output 7- VCC + 8 - Frequency compensation 1/8 |
